>I've been thinking about this this morning. Who invented the zero based approach, which applies to a lot of things in several development environments, including, among others, .NET. This is always a waste of time trying to understand/find which one applies to a specific component. I mean, when I start counting, I start at 1, right? lol

I imagine that it's because in the binary system, 11 only equals decimal 3 because 2^0 + 2^1 = 3. Otherwise, you'd have 2^1 + 2^2 = 6. If the 1st position isn't '0', then how would you represent decimal '1' in the binary system?
